``` specifies the type and allowable values of hyperparameters for a model configuration of type ```P```. For example, ```P``` could be a MultiLayerConfiguration for DL4J -- **Candidate Generator**: A ```CandidateGenerator``` is used to generate candidate models configurations of some type ```C```. The following implementations are defined in arbiter-core: - - ```RandomSearchCandidateGenerator``` - - ```GridSearchCandidateGenerator``` -- **Score Function**: A ```ScoreFunction``` is used to score a model of type ```M``` given data of type ```D```. For example, in DL4J a score function might be used to calculate the classification accuracy from a DataSetIterator - - A key concept here is that they score is a single numerical (double precision) value that we either want to minimize or maximize - this is the goal of hyperparameter optimization -- **Termination Conditions**: One or more ```TerminationCondition``` instances must be provided to the ```OptimizationConfiguration```. ```TerminationCondition``` instances are used to control when hyperparameter optimization should be stopped. Some built-in termination conditions: - - ```MaxCandidatesCondition```: Terminate if more than the specified number of candidate hyperparameter configurations have been executed - - ```MaxTimeCondition```: Terminate after a specified amount of time has elapsed since starting the optimization -- **Result Saver**: The ```ResultSaver``` interface is used to specify how the results of each hyperparameter optimization run should be saved. For example, whether saving should be done to local disk, to a database, to HDFS, or simply stored in memory. - - Note that ```ResultSaver.saveModel``` method returns a ```ResultReference``` object, which provides a mechanism for re-loading both the model and score from wherever it may be saved. -- **Optimization Configuration**: An ```OptimizationConfiguration``` ties together the above configuration options in a fluent (builder) pattern. -- **Candidate Executor**: The ```CandidateExecutor``` interface provides a layer of abstraction between the configuration and execution of each instance of learning. Currently, the only option is the ```LocalCandidateExecutor```, which is used to execute learning on a single machine (in the current JVM). In principle, other execution methods (for example, on Spark or cloud computing machines) could be implemented. -- **Optimization Runner**: The ```OptimizationRunner``` uses an ```OptimizationConfiguration``` and a ```CandidateExecutor``` to actually run the optimization, and save the results. - - -### Optimization of DeepLearning4J Models - -(This section: forthcoming) diff --git a/arbiter/arbiter-core/pom.xml b/arbiter/arbiter-core/pom.xml deleted file mode 100644 index ab5ded1b8..000000000 --- a/arbiter/arbiter-core/pom.xml +++ /dev/null @@ -1,97 +0,0 @@ - - - - - arbiter - net.brutex.ai - 1.0.0-SNAPSHOT - - 4.0.0 - - arbiter-core - jar - - arbiter-core - - - - net.brutex.ai - nd4j-api - ${project.version} - - - com.google.code.findbugs - * - - - - - com.google.guava - guava - ${guava.jre.version} - - - org.apache.commons - commons-lang3 - ${commons.lang.version} - - - - org.apache.commons - commons-math3 - ${commons.math.version} - - - - org.slf4j - slf4j-api - ${slf4j.version} - - - - joda-time - joda-time - ${jodatime.version} - - - - com.fasterxml.jackson.core - jackson-annotations - ${jackson.version} - - - - net.brutex.ai - deeplearning4j-common-tests - ${project.version} - test - - - com.fasterxml.jackson.datatype - jackson-datatype-joda - ${jackson.version} - - - net.brutex.ai - nd4j-native - ${project.version} - test - windows-x86_64 - - - diff --git a/arbiter/arbiter-core/src/assembly/bin.xml b/arbiter/arbiter-core/src/assembly/bin.xml deleted file mode 100644 index c99d6b144..000000000 --- a/arbiter/arbiter-core/src/assembly/bin.xml +++ /dev/null @@ -1,91 +0,0 @@ - - - - bin - - - tar.gz - - - - - - - lib - - *:jar:* - - - *:sources - - - - - - - - - readme.txt - - - - - src/main/resources/bin/ - bin - - arbiter - - unix - 0755 - - - - examples - examples - - - - - - - - target - ./ - - *.jar - - - - - - \ No newline at end of file diff --git a/arbiter/arbiter-core/src/main/java/org/deeplearning4j/arbiter/optimize/api/AbstractParameterSpace.java b/arbiter/arbiter-core/src/main/java/org/deeplearning4j/arbiter/optimize/api/AbstractParameterSpace.java deleted file mode 100644 index 4ff9dd964..000000000 --- a/arbiter/arbiter-core/src/main/java/org/deeplearning4j/arbiter/optimize/api/AbstractParameterSpace.java +++ /dev/null @@ -1,74 +0,0 @@ -/******************************************************************************* - * Copyright (c) 2015-2018 Skymind, Inc. - * - * This program and the accompanying materials are made available under the - * terms of the Apache License, Version 2.0 which is available at - * https://www.apache.org/licenses/LICENSE-2.0. - * - * Unless required by applicable law or agreed to in writing, software - * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT - * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
